A headgear suitable for wearing a respiratory mask system wearing on the head of a user is provided, wherein it can be easily manufactured, the leakage of the positive pressure gas when pressurized is reduced, and a good wearing feel is achieved. The headgear is adapted to secure a respiratory mask, which contacts the face of the user to supply a positive pressure gas for respiration to the user, to the head of user. The headgear has a head mounted portion which is worn on the occipital of the user and a strap (3) connecting to this head mounted portion. The head mounted portion has at least one closed curved belt (1) which has thereon at least one junction (2). At least one junction provides the closed curved belt with a nonplanar structure adaptable to the shape of the head of the user.
